Radeon HD 4890 1GB 124800 MB/sec
Difference: 3328 (3%)

Texel Rate

The GeForce GTX 560 will be a little bit (about 13%) more effective at texture filtering than the Radeon HD 4890 1GB. (explain)

GeForce GTX 560 45360 Mtexels/sec
Radeon HD 4890 1GB 40000 Mtexels/sec
Difference: 5360 (13%)

Pixel Rate

The GeForce GTX 560 is quite a bit (more or less 62%) more effective at FSAA than the Radeon HD 4890 1GB, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 560 25920 Mpixels/sec
Radeon HD 4890 1GB 16000 Mpixels/sec
Difference: 9920 (62%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
